Description
To connect to a database through PEAR::MDB, you have to create a valid DSN - data source name. This DSN consists in the following parts:
|
phptype: Database backend used in PHP (i.e. mysql , odbc etc.) |
|
dbsyntax: Database used with regards to SQL syntax etc. |
|
protocol: Communication protocol to use ( i.e. tcp, unix etc.) |
|
hostspec: Host specification (hostname[:port]) |
|
database: Database to use on the DBMS server |
|
username: User name for login |
|
password: Password for login |
|
proto_opts: Maybe used with protocol |
The format of the supplied DSN is in its fullest form:
phptype(dbsyntax)://username:password@protocol+hostspec/database |
Most variations are allowed:
phptype://username:password@protocol+hostspec:110//usr/db_file.mdb phptype://username:password@hostspec/database_name phptype://username:password@hostspec phptype://username@hostspec phptype://hostspec/database phptype://hostspec phptype(dbsyntax) phptype |
The currently supported database backends are:
mysql -> MySQL pgsql -> PostgreSQL ibase -> InterBase mssql -> Microsoft SQL Server oci8 -> Oracle 7/8/8i fbsql -> FrontBase |
With an up-to-date version of MDB, you can use a second DSN format
phptype(syntax)://user:pass@protocol(proto_opts)/database |
| Warning |
Please note, that some features may be not supported by all database backends. Please refer to the PEAR MDB extensions status document located at: <pear base dir>/MDB/STATUS to get a detailed list about what features are supported by which backend. |
